tubr_25a_n.jpg: An overview of the trunk shows the site of the described findings;
the undeveloped breasts lie on an imaginary line running in a curve from the axilla to the groin; they have a distinct areola and nipple. The same applies to similar structures situated caudally at different levels.
tubr_25b_n.jpg: On a close-up view an areola and a nipple is recognizable mainly within the left structure.
tubr_25a_n.jpg and tubr_25b_n.jpg: The diagnosis is bilateral polythelia which is residuals of developmental structures. For esthetic reasons these structures should be removed including a possible mammary gland.
